Returns:

getFont

public Font getFont(java.lang.String bitmapPath,
                    java.lang.String descriptionPath,
                    FontLoadListener listener)

Description copied from class: CanvasFactory

Get a font object for use with a canvas. This method is asynchronous and may issue non blocking requests to the server. Depending on the implementation, Font objects may be returned that are not yet initialised and an invocation of onLoad must be expected prior to using the font. Again, depending on the implementation, cached instanced may be returned immediately, and the onLoad listener will be invoked before returning the font object.

Specified by:

getFont in class CanvasFactory

Parameters:

bitmapPath - Path to the font bitmap.

descriptionPath - Path to the font descriptor

listener - Optional listener to invoke after font has been instantiated or when an error occured.

Returns:

Font
